When did you pass the exam?
Shouldn’t this be “When did you take the exam?” or “When did you sit the exam?” ?
The set of sentences on Tatoeba is quite confusing, as there are sentences in German with abgelegt and bestanden, and in English with pass and take.

That’s difficult.
“Wann haben Sie die Prüfung abgelegt?” (Vergangenheit!) implies a positive result but it is not as clear cut as “Wann haben Sie die Prüfung bestanden?”
Otherwise one would say:
“Wann haben Sie die Prüfung geschrieben?”
or more formal
“Wann sind Sie zur Prüfung angetreten?”
Literally “ablegen” means “lay aside” or “put away”.
